Abstract
A 66-year-old woman presented with symptoms of sudden onset of numbness, muscular weakness of bilateral lower extremities and urinary retention. Within 30 minutes after onset, she had complete flaccid paraplegia, and was transferred to the municipal hospital. MRI 5 days after onset revealed a swollen spinal cord and a low intensity area on T1 weighted sagittal images, and high intensity area on T2 weighted images in the anterior part of the cord below L1.
MRI 3 weeks after onset, showed a high intensity area in the anterior part of the cord on T1 weighted images and the cord was thinner than in the earlier images. After admission, motor recovery was seen, and she could walk with a cane eight months after onset, but there was no recovery of dissociated sensory loss below L1 on both sides, and urinary ratention.
